Abstract

Waste, if not managed properly, has the potential to reduce environmental quality. Kahayan River Watershed (DAS) it was concluded that the heavy metal content of Lead (Pb) was the highest. In Central Kalimantan, the water hyacinth plant (Eichornia crassipes) is a plant whose growth rate can threaten fish populations in rivers. The use of Water Hyacinth (Eichornia crassipes) is expected to reduce levels of the heavy metal pollutant Pb (Lead) in the water. The research method used is quantitative research. The test results showed that the Pb (Lead) concentration before treatment was significantly different from the concentration after treatment, this shows that the plants had a real effect in reducing the concentration of the heavy metal Pb in water. Based on the results of observations, it can be shown that there were morphological changes in the water hyacinth plants (Eichornia crassipes) from the beginning of the study until the 4th day. Water hyacinth (Eichonia crassipes) has been proven to reduce the heavy metal Pb (Lead) in the biotreatment of water polluted by the heavy metal Pb (Lead). Water hyacinth (Eichonia crassipes) reduces the heavy metal Pb (Lead) through the process of absorbing water by the roots, so that Pb (Lead) in the water is also absorbed. Then it is absorbed into the stem and spreads to the leaves of the Water Hyacinth plant (Eichornia crassipes).

Abstract

The quality of waste is tending towards more difficult types of waste, due to changes in food handling techniques and consumer goods that use non-degradable packaging such as plastic. Existing waste management concepts are sometimes not suitable for implementation. The waste generation in Gunung Mas Regency is 17.71 tonnes/day with an estimated waste generation of 0.9 litres/person/day and a waste specific gravity of 0.15 tonnes/m3. In urban areas it is 6.65 tons/day and in rural areas it is 11.07 tons/day, with the waste composition being 80% organic and 20% inorganic. The total amount of waste produced is 2426 tons/year and the amount disposed of in landfills is 2190 tons/year. This amount represents 90.27% of the total generation. The amount of unmanaged waste is 236 tons/year or 9.73% of the total generation. Waste management services are only available in urban areas, while 62.5% of unmanaged waste is generated in rural areas. The high value of managed waste in landfills is due to the lack of a processing or reduction function. Infrastructures that function as efforts to reduce waste are TPS 3R, TPST and Waste Bank. The existence of this infrastructure is the responsibility of all parties as it is related to the environment.
